Which manufacturer uses topper track for wooden coasters?

Rocky Mountain Construction (RMC) is notable for its innovative approach to wooden coaster design, particularly with the use of their topper track. This technology involves adding a steel track layer on top of a wooden support structure, allowing for smoother rides and the incorporation of modern inversions and elements that traditional wooden coasters can't easily achieve. By using topper track, RMC enhances the structural integrity of the coaster while maximizing the performance and ride experience. This approach has contributed to revitalizing many older wooden coasters, turning them into thrilling and highly sought-after attractions.
